which is ideal for short cycle loading. Caterpillar's 950M and 962M loaders have lock-up torque converters and locking front differentials. Refi ne- ments to Eco mode operation preserve more performance while further reducing fuel consumption. The 950M has a Z-bar linkage that also provides parallel lift capabilities, offering the best of both designs. And these loaders can run four hydraulic functions simultaneously instead of the more typical three functions. Lucas Sardenberg, wheel loader marketing consultant for Caterpillar, says sweep- ing is an example of an application where four functions prove helpful. The operator can move the broom side-to- side without articulating the machine. Volvo uses several technologies to attain reductions in fuel consumption of up to 18 percent in their L110H and L120H wheel loaders. Reverse by Braking (RBB) automati- cally reduces engine RPM and applies the service brakes when the operator changes directions. This reduces stress on the drivetrain while conserv- ing fuel. RBB is part of OptiShift, as is a lock-up torque converter. An eco pedal provides greater push-back, encouraging operators to keep the engine at its most effi cient speed. Product manager Eric Yeomans says three features on Volvo loaders make maintenance much easier. The entire aftertreatment assem- bly can be swung away with the removal of a few fasteners to improve service access. Rapid Oil Exchange (ROX) evacuates used oil from the engine, including the used fi lters, and then refi lls the system, including the new fi lters, with fresh oil. This makes for cleaner oil and fi lter servicing and ensures fi lters are pre-fi lled to prevent pressure loss upon startup. Grouped service points facilitate daily service checks. The rear axle cradle has lubricated-for-life bushings and bearings. Tier 4 Final The 457 is JCB's fi rst Tier 4 Final wheel loader. Where its predecessor used an 8.9-liter Cum- mins engine, the 457 has a 7.7-liter engine from MTU. Horsepower and torque are both up despite the drop in displacement, and Peter Gallagher of JCB says the smaller engine is a better fi t for the loader. "We leveraged the continuing march toward greater power density." And the Series 1000 in-line 6-cylinder meets Tier 4 Final regulations without a DPF. On its Tier 4 Final loaders, Komatsu uses SCR, which requires diesel emissions fl uid, or DEF. The DEF tank and lines are heated, and DEF is pulled from the lines back to the tank at shut-down to further protect against freeze damage. DEF consumption is about 2 percent of fuel use, helping Komatsu meet their goal of fl uid neutral or better (using the same or less total fl uids, fuel and DEF, as the fuel consumption of previous, non-SCR models). DEF level is shown on the cab monitor. Komatsu's Tier 4 Final machines also have Komatsu DPF. More than 98 percent of KDPF regeneration is done while the loader keeps working. EquipmentWorld.com | March 2015 25 Hyundai The HL740-9A is the newest model in Hyundai's lineup of 9A Series wheel loaders and features a 156-horsepower Cummins Tier 4 Interim QSB6.7 engine. The machine has three user- selectable modes for engine power and four for the automatic transmission. Optional confi gurations include extended reach for higher dump heights and tool carrier. A 3-cubic-yard bucket is standard. Deere John Deere offers the Loadrite 2180 on-board weighing system as a factory option on all 444K through 844K wheel loaders. Informa- tion such as total bucket loads, trucks loaded, and totals by material can be gathered and then shared via JDLink. All Z-bar and high-lift K Series loaders come pre-wired for easy installation of Loadrite 2180 if a customer chooses to add it later.
